Influence of sufentanil on lumbar anesthesia with ropivacaine

Objective To observe lumbar anesthesia with sufentanil plus ropivacaine in gynecological surgery and the impact of sufentanil on ropivacaine.Methods 80 patients undergoing gynecological surgery were randomly assigned to receive 0.5％ ropivacaine of 3ml alone ( group C,n =40 ) or 0.5％ ropivacaine of 3ml plus sufentanil of 2.Sug/ml ( group S,n =40 ).The hypalgesic level,analgesic level,time of onset of sensory block,time to blockade level at T10,time to extension of analgesis to cerebral side,time of onse of motor block,maximum time to motor block,Bromage scores on motor block,cases of intraoperative increases in dosage for anaesthesia,and adverse reactions were observed and recorded.Results Time of onset of sensory block,time to blockade level at T10,time to extension of analgesis to cerebral side,and time of onse of motor block were shorter in group S than in group C.The hypalgesic level and analgesic level were higher in group S than in group C.Fewer patients needed epidural increases in analgesics or addtional intravenous analgesics in group S than in group C.Fewer adverse reactions were found in group S.Conclusions In lumbar anesthesia with sufentanil plus ropivacaine for gynecological surgery,sufentanil increases time of onset of ropivacaine,enhances analgesic and anesthetic effects of ropivacaine,and has a lower rate of adverse reactions.
